Molded insole

ABSTRACT

A precast or molded insole for shoes adapted for use with several different heights of high heels comprising a main body, a first fiber board member formed to receive a preformed steel shank bonded to the bottom of the main body and a second fiber board member for nailing purposes bonded to the main body above said first fiber board member, said main body having a forepart shown as paddle-shaped, a shank depression in the first fiber board member extending longitudinally from in the heel area forwardly to about midway of the insole for the reception of a metal shank, and the like, after lasting, the heel portion rearwardly of the shank depression increasing in thickness. The insole is suitably contoured beneath for elimination of the use of a filler. A thin piece of paper product material is bonded to the forward two-thirds of the insole to assist in cementing the turned under portion of the upper or its lining and the outsole to the insole.

PATENIEU M1831 nan 3 601 908 lA/VEN Tole.- QANC/ M. GILKERSON,

MOLDED INSOLE BACKGROUND OF THE INVENTION SUMMARY OF THE INVENTION In brief, the present novel insole includes a main body having bonded to the bottom of the shank and heel portions a fiber board member having a longitudinal formed steel shank receiving recess extending from in the heel area forwardly approximately to the halfway mark of the insole break of the shank, the heel area rearwardly of the recess being of greatest thickness at the back and decreasing forwardly to the rear end of the recess, an integral filler portion on the bottom side of the insole being provided to eliminate the need of filler material. A heel nailing piece and a bottom forepart cementing piece are bonded to the main body.

Objects of the invention are to provide a novel insole which is adapted to be used with several heights of high heels without efiecting gaping at the back, which is made to receive a preformed metal shank, and the like, before the sole is attached and just before the heel is attached, which is streamlined to present a neat appearance, which obviates the use of filler, and which otherwise fulfills the objects and advantages sought therefor.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a top plan view of an insole incorporating the teachings of the present invention;

FIG. 2 is a bottom plan view thereof; and

FIGS. 3, 4, 5, 6, 7 and 8 are vertical cross-sectional views taken on substantially the lines 3-3, 4-4, 5-5, 6-6, 7-7, and 8-8, respectively.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawing more particularly by reference numerals, 10 indicates generally an insole incorporating the principles of the present invention. The insole 10 includes a main body 11 formed with a paddle-type forepart 12 of substantially uniform thickness except for a depending central area 14 adapted to obviate the necessity of bottom filler in the shoe. A fiber board member 15 is bonded to the bottom of the main body 11 and extends from the rear point thereof forwardly a little beyond midpoint, as indicated by the broken line in FIG. 2. An elongated recess 16 is provided in the member 15 which extends from about midway of the heel portion 18 of the main body It forwardly to a point substantially midway of the main body 11, the recess 16 extending within the area of the thickened filler portion. The heel portion 18 from a rear point 20 of the recess 16 to a rear point 22 of the heel portion 18 gradually increases in thickness, as is clear from FIGS. 3 and d. This increase in thickness permits several heights of high heels to be applied to the heel portion 18 without gaping at the rear; that is, in proper treading relation. A steel shank, or the like, can be placed in the recess 16 before an outsole and/or a heel has been applied to the heel portion 18, which permits forming of the shank before insertion into the recess 116, so that it may have the proper curvature for the particular height of heel applied. It is not practical to bend shanks once molded into an insole. A fiber board heel nailing piece 24 and a think bottom cementing piece 26 of paper, or the like, are bonded to the main body 11, as shown, the latter being illustrated en- .larged as to actual thickness to permit cross sectioning, being much thinner than the fiberboard piece M.

It is manifest that there has been provided an insole which fulfills the objects and advantages sought therefor.

It is to be understood that the foregoing description and the accompanying drawing have been given by way of illustration and example. It is also to be understood that changes in form of the elements, rearrangement of parts, and substitution of equivalent elements, which will be obvious to those skilled in the art, are contemplated as within the scope of the present invention which is limited only by the claims which follow.
